Low and High Energy Neutrinos from SN 2023ixf in M101

TL;DR

This paper investigates the potential for detecting high- and low-energy neutrinos from the nearby supernova SN 2023ixf, constraining jet models and neutrino production theories through non-detections and sub-threshold estimates.

Contribution

It provides the first constraints on neutrino emission from SN 2023ixf, combining observational limits with theoretical models for neutrino production in supernova jets.

Findings

No high-energy neutrinos detected by IceCube.

Constraints placed on jet production fraction in stellar collapses.

Sub-threshold estimates for low-energy neutrino detection by Hyper-Kamiokande.

Abstract

Supernova (SN) 2023ixf in M101 is the closest SN explosion observed in the last decade. Therefore it is a suitable test bed to study the role of jets in powering the SN ejecta. With this aim, we explored the idea that high-energy neutrinos could be produced during the interaction between the jets and the intense radiation field produced in the SN explosion and eventually be observed by the IceCube neutrino telescope. The lack of detection of such neutrinos has significantly constrained both the fraction of stellar collapses that produce jets and/or the theoretical models for neutrino production. Finally, we investigated the possibility of detecting low-energy neutrinos from SN 2023ixf with the Super- and Hyper-Kamiokande experiments, obtaining in both cases sub-threshold estimates.
